Thanks very much

There is a activex written using MFC and COM .
The main class inherits
CComObjectRootEx
IDispatchImpl
CComCoClass
IObjectSafetyImpl
Now 2threads are created inside this class in the constructor.
When IE is refreshed/reloaded, I loss the pointer of the process and
threads are not deallocated.
So what I did is, made thread ID's as static in the class and
deallocate them in the constructor before creating new threads.
When I WaitforSingleObject() I always get time out(258).
so I call TerminateThread().
I know this is wrong way.
Now this method is leaving lot of leaks.
Please suggest me a remedy so that I can trap the refresh ask my thread
to exit gracefully.
Thanks a lot in advance.

Do not include winbase.h directly in your code. Include windows.h which indirectly includes winbase.h. Windows.h declares a bunch of stuff that winbase.h needs.
You may be right

what's the use of this in a code of programs?
i'm just asking because it was used in the code of magic square..

Your question is not clear!
Are you asking about this keyword?
this pointer is a pointer that is accessible within member functions (that are not static) of a class. It denotes the object for which the member function was called.

this is legal only in a member function, and is a pointer to the object that the method is being called on.
You don't see it a whole lot in C++, however for some reason in C#, it seems to be the convention to use this. when accessing member variables.

 what is the use of #include<vecto>? thanks
|
|
|
|

The #include directive tells the preprocessor to treat the contents of a specified file as if those contents had appeared in the source program at the point where the directive appears. You can organize constant and macro definitions into include files and then use #include directives to add these definitions to any source file. Include files are also useful for incorporating declarations of external variables and complex data types. You need to define and name the types only once in an include file created for that purpose.
Look here[^] for more details.

Add in previous msg
The main advantage of #include is you can use one code in many programe without copying every time.

hi everyone
I have a problem in this code. I have to write a program that reverses a given file that is it will start reading the first half of the file, and continue to read the second half and replacing it with the reversed first half. It will end the operation by going to the beginning of the file and filling the first half with the reversed second half
I am having problem with reversing the second half and filling it in the first half's position (the second part of the question)
following is what i have done till now
any help would be greatly appreciated!!
thanks for your time!
#include <fcntl.h>
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
int main(){
int fh;
long pos; /* Position of file pointer */
char buffer[10];
char *d = new char[10];
char buffer1[10];
int a,b,end,middle,i,j,p,count,m;
fh = open("abf.txt", O_RDONLY,0);
/* Seek the beginning of the file: */
pos = lseek( fh, 0L, 0);
if( pos == -1L )
perror( "_lseek to beginning failed" );
else
printf( "Position for beginning of file seek = %ld\n", pos );
end = lseek( fh, 0L, 2 ); /*end of the file*/
if( end == -1L )
perror( "_lseek to end position failed" );
else
printf( "Position for end position seek = %ld\n", end );
middle = end/2;
printf("middle of the file is:%d\n",middle);
for(i=0;i

Can you not read the input file into a buffer, reverse the buffer (e.g., strrev()), and then write it to the output file?

here's the problem......at any given time only half of the file can be in memory and the other part in buffer, the buffer already has the first half, all it has to do is overwrite it with the reversed second half but instead the pgm is just overwriting it with the second half not the reversed second half
Thanks!
char buffer[10];
char *d = new char[10];
fh = open("abf.txt", O_RDONLY,0); /* Seek the beginning of the file: */
pos = lseek( fh, 0L, 0);
end = lseek( fh, 0L, 2 ); /*end of the file*/
middle = end/2;
printf("middle of the file is:%d\n",middle);
for(i=0;i {
p=lseek(fh,0L,0);
read(fh,buffer,middle);
printf("character read iin buffer is %c\n", buffer[i]);
}
count=lseek(fh,middle,0);
printf("buffer's characters are %c,%c,%c\n",buffer[0],buffer[1],buffer[2]);
i=2,j=0;
for(j=0;j

Huh? Where else could the buffer reside if not in memory?
While it obviously wouldn't be the most efficient, how about using two variables: one to start at the beginning of the file, and the other to start at the end of the file? Read a character into each, swap them, write them back to disk, advance the two variables until they meet in the middle.
Another idea is something like:
void main( void )
{
char szBuffer[] = "ABCDEFGHIJKLMNOPQRS";
char *psTemp;
int x,
y;
psTemp = new char[strlen(szBuffer) / 2];
for (x = 0; x < 10; x++)
psTemp[x] = szBuffer[x];
for (y = 0, x = strlen(szBuffer) - 1; x >= strlen(szBuffer) / 2; x--, y++)
{
char c = szBuffer[x];
szBuffer[x] = psTemp[y];
psTemp[y] = c;
}
for (x = 0; x < strlen(szBuffer) / 2; x++)
szBuffer[x] = psTemp[x];
}
